WILLIAM H. CURTIS, 'OF PORTLAND, OREGON.

FURNACE-FEEDER.

To all LU/M1711, lib may cancer/L.-

Be it known that I, WILLIAM H. CURTIs, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Furnace-Feeders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in fuel-feeding apparatus which are employed for feeding shavings, sawdust, and other material to places of storage or to furnaces where they are consumed as fuel for generating steam for driving the machinery connected to the boilers of said furnaces. Heretofore this kind of fuel has been taken up by suitable fans from the machines where it has been made and from there conveyed to a separator, by means of which a large portion of the air is permitted to escape and the fuel material brought into a more compact mass, so that it can be divided and directed into any desired pipe or pipes to be conveyed either to the furnaces or to a suitable place of storage, such disposition of the material from one point to another being controlled by checkvalves located in said pipes.

In practical use and operation it has been found that while sawdust, short shavings, and other small particles can be successfully conducted to the furnace or place of storage it has also been found that it is very diflicult, if not almost impossible, to so feed or conduct long shavings or refuse produced in cooperage or other factories to the desired points, owing to the liability of such long shavings or splints catching upon the edges of the dividing-valves in the pipes and forming a compact and unyielding mass at such points, thus preventing the proper feeding of the said material.

It is the object of my invention to obviate this difficulty and to provide reliable means for feeding such material directly to either of two or more furnaces or storage-places and. to change the feed from one furnace to another in the simplest and best possible manner.

To these ends my invention consists, essentially, of an adjustable pipe provided with a hinged and a telescopic section adapted. for operation in connection with a receiving-seetion having an upwardly-projecting flange or rim at its upper part and provided with two or more delivery-pipes connecting with openings in its bottom and leading therefrom to the furnaces or storage-places, whereby a continuous supply of fuel material is fed direct from a suitable source of supply to the desired furnace.

My invention consists, further, in the novel details of construction and general arrangement of parts, which will be hereinafter described, and pointed out in the claims.

My invention will be more fully understood by reference to the accompanying drawings, wherein the same parts are indicated by like letters throughout the several views, and in which- Figure 1 is a front elevation of a portion of a furnace, showing my apparatus applied thereto. Fig. 2 is a sectional view of the adjustable pipe, receiving-section,and the delivery-pipes; and Fig. 3 a longitudinal sectional view of the receiving-section and its connecting-pipes.

Referring to said drawings, the letter A indicates the separator or collector for the fuel material, and B the rigid feed-pipe leading therefrom.

C represents the hinged section of pipe connected to the pipe B by the swing-hinges (.6 a, one on each side, as shown. Upon the lower end of this section C is provided a sliding sleeve or telescopic section I), which is adapted to be moved upwardly or downwardly thereon by means of the long handle E, the upper end of which is rigidly attached to said section, as shown.

F represents the receiving-section provided with two or more deliveryapes (i, connecting with openings in its bottom and leading thcrefrom to the furnaces H. In this application I have shown three of these pipes (Jr; but the number of delivery-pipes employed must be governed by the number of the furnaces to be used. An upwardly-projecting flange or rim manner: WVhen it is desired to deflect the fuel material from one delivery-pipe Gr to another, the handle E is operated to first raise the sliding sleeve or telescopic section D out of engagement with the mouth of the delivery-pipe (i which is being fed, and then by means of said handle the telescopic section I) is swung either to the right or to the left to contact with the open mouth of the delivery-pipe into which it is desired to deflect the fuel material, and finally said handle is pulled down to securely seat the lower open end of the telescopic section into the mouth of the deliverypipe to convey the fuel to its connecting-furnace. This operation may be repeated at pleasure and the fuel-supply continuously directed into either one of the delivery-pipes to feed its connecting-furnace Without any liability of clogging or choking the feed or delivery pipes, there being no valves or other obstructions in said pipes to prevent a continuous and direct feed from the source of supply to the furnace.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a fuel-feeding apparatus, the combination of a plurality of delivery-pipes, a feeding-pipe communicating with a suitable source of supply, and a swinging tubular member comprising a hinged section and a telescopic section; said member adapted to be brought into communication with either of said delivery-pipes, substantially as and for the purpose specified.

2. An apparatus for providing acontinuous direct feed of the fuel from the source of supply to either of two or more combustionchambers, comprising the feed-pipe B, the section G pivotally connected thereto, the section D in telescopic relation with said section 0, the handleE attached to the section D, and a receiving-section F, having an inclosing flange or rim at its upper part, and openings in its bottom, and provided with two or more delivery-pipes G, connecting with said openings and leading therefrom to the combustionchambers, substantially as and for the purpose specified.

3. In a fuel-feeding apparatus, the combination of a suitable source of supply, a feed-- pipe, a tubular section hinged thereto, a telescopic section movable thereon, a handle for operating said hinged and telescopic sections, and means for delivering the material from said telescopic section to either of a plurality of combustion-chambers, substantially as and for the purpose specified.

4:. In a fuel-feeding apparatus, the combination with the source of supply, a feed-pipe, a tubular section hinged thereto, a telescopic section movable thereon, and a handle for operating said hinged and telescopic sections, of

a receiving and delivery section comprising a' holding-receptacle having an inclosing rim or flange, and provided with openings in its bottom, and two or more delivery-pipes secured within said openings; said parts providing a free passage for the fuel material, substantially as specified.

5. In a fuel feeding apparatus, the combi nation with the source of supply anda hinged pipe, of a receiving-section comprising atop part having an upwardly-extending flange or rim, and openings in its bottom,delivery-pipes having their upper ends received in said openings and their lower ends extending to the combustion-chambers, substantially as specified.

6. In a fuel-feeding apparatus, the combination With the source of supply, and its feedpipe B, its section 0 hinged thereto, and the sliding sleeve or telescopic section D, adapted to move upon said section C, and provided with the handle E, of a receiving-section F, having an upwardly-projecting flange or rim F, and provided with two or more deliverypipes Gr, connecting with openings in its bottom and leading therefrom to the combustionchambers, substantially as specified.

7 A fuel-feeding apparatus for feeding fuel directly from a source of supply to a furnace, comprising a stationary feedpipe B,eonnected to the source of supply, a tubular swinging member hinged thereto comprising a hinged section U and a telescopic section D, a handle E for directing said swinging member, and means for delivering the material from the swinging member to either of a plurality of combustion-chambers, substantially as speci In testimony whereof I afliX my signature in presence of two witnesses.
